Compile and upload the binary

This guide assume that the port number is COM3. It might be different from yours.

Verify and compile the sketch. This can be done by clicking Sketch → Verify/Compile menu or by pressing CTRL-R shortcut.

If the compiling completes without any issue, upload the compiled binary by clicking Sketch → Upload or by pressing CTRL-U shortcut.

You can omit the compile process since its done automatically when you just upload without doing a compile before.
You will know the uploading is complete by the message: “Hard resetting via RTS pin…”.

Upload the data

This example has a web server program to serve measurements via a web page.
To see that page, you have to upload the web page data to the ODROID-GO's flash memory.SPIFFS lets you do that.

If you click the Tools → ESP8266 Sketch Data Upload menu, SPIFFS utility will find the data directory in the current library and send it.

Click the menu to upload.
The uploading is complet when the message “Hard resetting via RTS pin…“ is displayed.

Check if it works

After the upload completes, ODROID-GO reboots automatically.

The screen showing each data measurement appears on the ODROID-GO, and after few seconds, the blue LED in the middle of the board turns on.

Visit with your device - PC / mobile

The blue LED indicates that the web server on the board is ready so that you can connect to it and read the data from the ODROID-GO's access point.

Find the Wifi AP named ODROID_GO_**** and connect to it.
The default password is 12345678.

Open a web browser and navigate to 192.168.4.1. This IP address is set by default.
You can see the web GUI showing each measurement, and the blue LED now keeps blinking after the socket communication starts.

You can set the Wifi configurations such as SSID, IP address, and password.
